Highway has not only promoted the economic development of China, but also brought about prodigious convenience to our daily life.However, highway construction will produce problems such as soil erosion, water loss and destroying of the natural environment.The article analyses the soil erosion, water loss in the construction of Jieliang highway, and forecasts the new loss of the soil in the construction period.The America Universal Soil Loss Equation (USLE) is chosen to forecast the soil loss in construction area.Through calculation, it is anticipated that the new soil loss in construction period is 81.2×103t.According to the characteristics of the project, the construction region is plotted into several areas with corresponding prevention measures for each area.It is expected that 115.8×103t of soil loss can be controlled after the corresponding prevention measures have been implemented.
